Outcomes
Primary outcome [1] 318974 0
Evaluation of postoperative shivering incidence.The shivering will be assessed according to the scale: Grade 0, no shivering; grade 1, no visiblemuscle activity; grade 2, muscular activity in only one muscle group; grade 3, moderate muscular activity in more than one muscle group; grade 4, violent muscular activity that involves the whole body.The patients will be judged to have shivering if they evaluate as grade 3 or 4.

Summary
Brief summary
The patients will continuously observe for the occurrence of postoperative shivering (PS) for the first 5 minutes after the arrival to the PACU and then for every 3 minutes during the stated period in the PACU. Core and peripheral temperature will be evaluated. Demographic data, type of drug taken and medical history will be recorded. In addition, shape and duration of surgery, duration of anesthesia, anesthesia application, agents used in anesthesia induction and care, airway devices, fluids, urine output, blood loss, blood transfusion, vasopressor use, irrigation fluid usage, analgesic use, antiemetic use and adjuvant drug use will be saved.
